SPECIFICATION formingpart of Letters Patent No. 774,197, dated November8, 1904. Application filed October 9, 1902. Serial No. 126,416. (Nomodel.)

To all 1072,0717, it may concern.-

Be it known that 1, JOHN S. PINNELL, a citizen of the United States,residing at Crossville, in the county of Cumberland and State ofTennessee, have invented certain new and useful Improvements in Puzzles,of which the following is a specification.

My invention relates to puzzles.

It has for its object to provide a puzzle comprising a cubical blockmade up of a plurality of individual oblong rectangular notched andplain blocks.

It has for a further object to provide a block of the characterdescribed requiring skill, patience, and ingenuity to place theindividual blocks together to form the cubical block, thereby serving asan amusement and pastime.

In the drawings, Figure l is a perspective view of the cubical block.Figs. 2, 3, and 4 are elevations looking at three faces of the eubicalblock. Figs. 5, 6, 7, and 8 are detail perspective views of theindividual blocks which are placed together to form the eubical block.

Corresponding parts in all the figures are denoted by the same referencecharacters.

Referring to the drawings, 1 designates individual oblong rectangularblocks the vertices of the angles of which are continuous anduninterrupted; 2, individual oblong rectangular blocks each havingnotches 2 cut in the vertex of one angle, leaving a part 10of its vertexintermediate each notch and a part 11 at the ends; 3, individual oblongrectangular blocks each having notches 3 cut in the vortex of one of itsangles, leaving a part 12 of its vertex at each end and forming anuninterrupted -series of diamond-shaped projections between said ends;4, individual oblong rectangular blocks each having notches 4 out in thevertex of one angle, leaving a part 13 of the vertex at each end andforming an uninterrupted series of diamond-shaped projections betweensaid ends and notches 4 cut in the vertex of another angle thereof,leaving a part 14 of the vertex at each end and a part 15 of its vertexbetween said notches.

The cubical block, which is constructed of the notched and plain blocksabove described in detail, comprises four horizontal superposed seriesof blocks 3, the blocks of each series arranged side by side, so thatthe vertices of the angles having the notches 3 will contact and thenotches register to formvertical holes; four vertical series of blocks4, the blocks of each series arranged one above the other, so that thenotches 4 will engage alternate diamond-shaped projections of the blocks3 between the notches 3 and the notches 4 register with the notches 3 inthe blocks 3, two of said blocks 4 being interposed between each seriesof blocks 3 and one located on each outside series at the pointsmentioned; vertical blocks 3 located in the vertical holes in the endsof the horizontal series of blocks 3. outside the two end verticalseries of blocks 4, the notches in the vertices of the angles of saidvertical blocks 3 engaging the vertices of the angles of the end blocks4, and vertical blocks 3 located in the vertical holes in the series ofblocks 3 intermediate the two middle vertical series of blocks 4, thenotches in the vertices of the angles also engaging the vertices of theangles of the blocks 4; vertical blocks 2 located in the re' mainingvertical holes in the series of blocks 3 intermediate the two middlevertical series and the two outside vertical series of blocks 4, and thevertices of the angles having the notches 2 contacting and the notchesregistering to form horizontal holes, and horizontal blocks 1 located inthe horizontal holes formed by the notches of the vertical blocks 2. Itwill therefore be understood that to form this cubical block six blocks1', sixteen blocks 2, thirty-two blocks 3, and forty-eight blocks 4 areemployed and that the blocks 2 form the key-blocks.

1 do not desire to be understood as limiting myself to the details ofconstruction and arrangement as herein described and illustrated, as itis manifest that variations and modifications may be made in thefeatures of construction and arrangement in the adaption of the deviceto various conditions of use without departing from the spirit and scopeof my invention and improvements. I therefore reserve the right to allsuch variation and modification as properly fall within the scope of myinvention and the terms of the following claim.

Having thus described my invention, I claim and desire to secure byLetters Patent- A puzzle comprising a cubical block formed of aplurality of rectangular blocks the vertices of the angles of each ofwhich are uninterrupted, a plurality of rectangular blocks the vertex ofone angle of each of which is interrupted at intervals by notchesleaving portions of the vertex between said notches and at the ends ofthe block undisturbed, a plurality of rectangular blocks the vertex ofone angle of each of which is interrupted by notches leaving portions ofthe vertex at the
